org.apache.tika.parser.ocr.tess4j.Tess4JConfig

org.apache.tika.parser.ocr.tess4j.Tess4JConfig.RuntimeConfig

All Implemented Interfaces:

Serializable

Enclosing class:

Tess4JConfig

public static class Tess4JConfig.RuntimeConfig
extends Tess4JConfig

Runtime-only Tess4JConfig that prevents modification of paths and pool settings during parse-time configuration.

Always blocked: dataPath, nativeLibPath, poolSize.

Paths are blocked to prevent file-system access attacks. Pool size is blocked because the pool is built at init time and cannot be resized at runtime.

setDataPath

public void setDataPath(String dataPath)
                 throws TikaConfigException

Description copied from class: Tess4JConfig

Set the path to the tessdata directory.

Overrides:

setDataPath in class Tess4JConfig

Throws:

TikaConfigException

setNativeLibPath

public void setNativeLibPath(String nativeLibPath)
                      throws TikaConfigException

Description copied from class: Tess4JConfig

Set the path to the directory containing native Tesseract/Leptonica shared libraries. On macOS with Homebrew this is typically /opt/homebrew/lib.

Overrides:

Throws:

TikaConfigException

setPoolSize

public void setPoolSize(int poolSize)

Description copied from class: Tess4JConfig

Set the number of Tesseract instances to keep in the pool. Default is 2. Must be at least 1.

Overrides:

setPoolSize in class Tess4JConfig

setMaxImagePixels

public void setMaxImagePixels(long maxImagePixels)

Description copied from class: Tess4JConfig

Set the maximum total pixels (width × height) allowed for an image before OCR is skipped. Default is 100,000,000 (100 megapixels). Set to -1 for no limit (not recommended).

Overrides:
